Importance
Vapor pressure is a critical physical property for volatile liquids, significantly impacting automotive and aviation gasoline performance. It affects vapor resistance during startup, heating, and high-temperature or high-altitude operations. In some regions, maximum vapor pressure limits for gasoline are legally enforced to prevent air pollution. For crude oil, vapor pressure is crucial for production, refining operations, and initial processing. It can also serve as an indirect measurement of the volatilization rate of volatile petroleum solvents.
